And now, imagine your car avoiding a crash by talking to the other cars around you. Today, the U.S. Government said there is a new technology they want you to have. Maybe by the time you buy your next car. Something as important to safety as seat belts. ABC's David Kerley shows us how it works. Reporter: Our cars are designed to survive this. But what if we could keep most of those accidents from ever happening? Like we saw in that super bowl ad last night, with a distracted teen driver. Tonight, the next step. A plan that could cut accidents by 80% by having your car talk to the other cars around you. I don't think you can understate the significance of having vehicles that are smart enough to realize when an accident is going to happen and they're able to stop it. Reporter: The government plans to require that every new car have vehicle-to-vehicle technology, a new rule in place by the end of 2016. Here's how it works. Ten times every second, your car will transmit its speed, direction and other information and it will receive the same information from cars around it. So, if someone is braking hard several cars in front of you, coming around a corner, or trying to pass another vehicle, you will get a warning. This talking cars technology, estimated to cost between $100 to $200 per vehicle, will only warn. The driver will still have to act. But in the future, it could be paired with other systems, like those automatic brakes, which we tried out on a test track. And it just takes ove everything. Just amazing. You can really build a foundation of avoiding crashes before they happen in the first place. Reporter: Car talk, that could save at least 20,000 lives on American highways every year. David Kerley, ABC news, Washington.
